Re: Hummingbird -- the littlest dinosaur!
And if turtles are lepidosauromorphs or archosauromorphs, then
_Reptilia_ sensu Gauthier becomes exactly the same clade as _Sauria_
Not if we accept this emendation:
Sean P. Modesto & Jason S. Anderson: The Phylogenetic Definition of
Reptilia, Systematic Biology 53(5), 815 -- 821 (I think October 2004)
"the most inclusive clade containing *Lacerta agilis* Linnaeus 1758 and
*Crocodylus niloticus* Laurenti [sic] 1768, but not *Homo sapiens* Linnaeus
That's a synonym of Sauropsida. The authors know this -- and like Reptilia
better than Sauropsida because the former name is more widely used (although
in a different meaning!). The paper contains further peculiar statements,
like the following (p. 818):
"The removal of 'pelycosaurs' and therapsids (the 'mammal-like reptiles' of
previous parlance) from Reptilia was accepted long ago because these taxa
clearly form a lineage (leading to mammals) separate from the other groups
of amniotes [...]."
Plenty of zoologists, including herpetologists, have never heard of the
phylogenetic definition of Reptilia, and I bet that most that have heard of
it hate it (and all phylogenetic nomenclature with it)! "Long ago"? Like
"minus twenty years ago"?
